With the changes you have made, the following code will fail:
Object* a = new Transform();
Transform* b = dynamic_cast<Transform*>(a->clone());
assert(b);
Will it? Just playing Devil's advocate here, I don't care either way,
and I may be showing my poor C++ skills, but since the clone() method
is virtual, a->clone() will return a Transform* (with Valery's
changes), and dynamic_casting a Transform* to a Transform* will just
be a no-op and return the same object, so the assert will not fail...
Or am I seeing this wrong?
To my knowledge, the code will fail because the c++compiler will call
osg::Object::clone and not osg::Transform::clone because the function
signatures differ (they return different types of objects).
cheers,
